Project Overview and Engineering Alignment
The Chennai Port to Maduravoyal Elevated Corridor is a flagship infrastructure initiative engineered to alleviate heavy container congestion across Chennai's metropolitan road network.
Built predominantly along the alignment of the Cooum River, the 20.6-kilometer corridor features an innovative double-decker elevated viaduct design, separating local city vehicular traffic on the lower tier from port-bound heavy commercial trucks on the upper tier.
- Total corridor length: 20.6 kilometers of elevated viaduct connecting Chennai Port Gate No. 10 to Maduravoyal
- Double-decker design: Lower deck for local urban transit; upper tier reserved for port-bound heavy commercial container traffic
- Implementing agency: National Highways Authority of India (NHAI) under the Ministry of Road Transport and Highways
- Interchange connectivity: Directly connects Chennai Port with National Highway 48 (Chennai-Bengaluru Highway)
Agro-Commodity Export Logistics and Hinterland Transit
Chennai Port serves as a primary maritime gateway for agricultural and processed food commodity exports from southern India.
The elevated expressway provides uninterrupted 24/7 container transit, drastically cutting transit times for agricultural freight—including export shipments of non-basmati rice, spices, processed food products, marine seafood, and tobacco.
- Export commodities: Rice, spices, processed gherkins, mango pulp, marine fisheries, and tobacco
- Turnaround time: Reduces container transit time between the port and NH-48 from several hours down to under 30 minutes
- Elimination of congestion: Bypasses inner-city daytime commercial vehicle entry bans completely
- Port efficiency: Eliminates container congestion at harbor gates, boosting vessel turnaround speeds
Economic Impact and Regional Supply Chains
By seamlessly linking the port with industrial logistics parks, inland container depots (ICDs), and agro-processing clusters across Sriperumbudur, Oragadam, and the Bengaluru industrial corridor, the expressway strengthens regional export supply chains.
The corridor integrates with the PM Gati Shakti National Master Plan, providing multi-modal logistics synchronization across road, rail, and maritime shipping channels.
- Multi-modal integration: Aligned with PM Gati Shakti principles linking maritime docks with rail and road networks
- Hinterland reach: Connects manufacturing and farming hubs across Tamil Nadu, Karnataka, and Andhra Pradesh
- Reduced logistics cost: Cuts diesel idling emissions and operational transportation costs per container
- Economic growth: Catalyzes warehousing, cold-storage, and fulfillment hub development along connecting highways
